I've had a cold now for a week, but luckily it's not bad. Sometimes I don't even notice it, but sometimes it is a little annoying. But I'm thankful it's not as bad as my last one.

One time my dad was coughing really bad too and he popped a blood vessel in his eye, but I don't think he noticed it because my mom was the one who pointed it out.

I suggest cough medicine, but if you prefer not to take medicine [I usually like to let my body do it itself too] then I'd say the best thing to do is give it time. It'll eventually pass on.
